Compliance with these actions is mandatory to continue safe operation of affected Falcon 7X, 2000EX, and 900EX aeroplanes.
Summary
EASA Airworthiness Directive 2017-0240R1 is an amendment addressing barometric setting operational limitations and Master Minimum Equipment List updates for Dassault Aviation Falcon 7X, 2000EX, and 900EX aeroplanes. It applies to specific serial numbers excluding those with certain Dassault modifications or service bulletins. The directive aims to mitigate risks related to erroneous barometric settings caused by a temporary defect in the Cursor Control Device affecting flight safety.
What changed
This revision excludes Falcon 7X aeroplanes that have embodied Dassault modification M1969 or service bulletin F7X-521 from the applicability, confirming that these modifications remove the operational restrictions. It updates the original AD 2017-0240 by incorporating the new corrective actions and associated software load certified by Dassault Aviation.
Why it matters
This directive is critical for aviation professionals as it addresses a potential unsafe condition that could lead to incorrect flight altitude readings, impacting safe flight and landing. Operators and maintenance teams must ensure compliance to prevent navigation system errors caused by faulty barometric settings. The amendment also clarifies when operational restrictions can be lifted following specific modifications, aiding in fleet management and compliance.
